TUNNEL-BASED METHOD OF AND SYSTEM FOR IDENTIFYING TRANSPORTED PACKAGES EMPLOYING THE TRANSMISSION OF PACKAGE DIMENSION DATA OVER A DATA COMMUNICATIONS NETWORK AND THE TRANSFORMATION OF PACKAGE DIMENSION DATA AT LINEAR IMAGING SUBSYSTEMS IN SAID TUNNEL-BASED SYSTEM SO AS TO ENABLE THE CONTROL OF AUTO ZOOM/FOCUS CAMERA MODULES THEREWITHIN DURING LINEAR IMAGING OPERATIONS
A camera-based tunnel-type package identification system comprising at least first and second camera units, a package dimension subsystem, and a data communications network installed about a conveyor belt structure. Each camera unit is mounted about the conveyor belt structure, and has a linear imaging subsystem with a field of view (FOV) having automatic zoom and focus imaging optics, and a camera control computer for controlling the operation of the imaging subsystem. During system operation, package dimension data from transported packages is transmitted over the data communications network to the first and second camera units. Each camera control computer converts received package dimension data to its local coordinate reference system, and generates camera control signals which drive the automatic zoom and focus imaging optics of its associated camera units to enable the capture and processing of linear images of the transported package.
